摘要：
Diazonium compounds are disclosed which correspond to the formula ##STR1## in which Y' is vinyl, .beta.-hydroxyethyl of an ethyl group having a substituent in the .beta.-position which is eliminated by means of alkali, R is hydrogen, hydroxy, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, carboxy or halogen, n is the number 0, 1 or 2, M is hydrogen or an alkali metal, and An is an anion, and wherein the diazonium group is bound in the meta- or para-position to the nitrogen of the benzotriazole radical.Also disclosed is a process for the preparation of the diazonium compounds. The compounds are useful as diazo components for the preparation of azo compounds by a coupling reaction.
